I don't know. Maybe.

If you can send a profile log to the list, maybe someone could suggest 
something.

Look at suspect LargeInteger methods and see if they call the primitives.

You can comment out the primitive calls in specific methods if you want to see 
how much slower it is *without* the plugin.

But usually it's not the fault of the plugin in cases like this. It sounds to 
me like maybe there's too much garbage collection going on, or too many 
unnecessary conversions, or something.

For instance, if you're using SortedCollection for big collections of DateTime 
instances that are being changed a lot, you should probably be using some 
other kind of collection that's more efficient.

You use them. When a method in one of them is needed, it's loaded.

I don't know how you would.
